A week might be over optimistic.This is about attacking a military that has known that we'll be coming for more than a year.
Idiots like flashy new weapons.
But it all comes down to soldiers.
We can take out command and control in less than a day. That just means that all those divisions and brigades and battalions and companies are operating with only their internal command structure.
Dropping a bomb on HQ is not going to soften up a tank company.
That's why we bombed them for so long before we went in last time. We deprive them of sleep and food and supplies for long enough and they'll be ready to surrender when we do move.
